Big Ron's revenge and Arsenal's late cock-up.... Sportsmail looks back at the most famous League Cup final upsets

Ahead of Sunday's Capital One Cup final between Manchester City and Sunderland at Wembley, Sportsmail takes a look back at some of the most famous League Cup final upsets.

QPR 3 West Brom 2 March 4, 1967 l Att: 97,952

West Brom were the defending champions and playing in the top flight when they took on Third Division QPR at the first League Cup final to be held at Wembley. When Clive Clark scored twice in the first half, West Brom looked odds on to retain the trophy, but goals after the break from Roger Morgan, Rodney Marsh and Mark Lazarus gave QPR a famous win.

But flu upset their preparations and the Horse of the Year Show earlier in the week turned Wembley into a mudbath.

Roger Smart put Third Division Swindon ahead but Bobby Gould sent the game into extra time.

Don Rogers scored twice for a shock win.

Nottingham Forest 0 Wolves 1March 15, 1980 l Att: 96,527

AS European champions and League Cup holders, Brian Clough’s Forest were clear favourites. But they met with fierce defensive resistance from Wolves. Striker Andy Gray scored the only goal, tapping into an empty net after goalkeeper Peter Shilton and defender David Needham collided trying to clear a long ball.

Luton Town 3 Arsenal 2April 24, 1988 l Att: 95,732

Defending champions Arsenal were favourites to win the trophy again and, despite Brian Stein’s early goal for Luton, established a 2-1 lead thanks to Martin Hayes and Alan Smith. But a scrappy late goal from Danny Wilson and an even later one from Stein gave Luton the first major trophy in their history.

Man Utd 0 Sheffield Wed 1April 21, 1991 l Att: 77,612

Wednesday boss Ron Atkinson had been sacked by United five years earlier and nobody expected his Second Division side to win. A first-half shot off a post from John Sheridan gave Wednesday their one and only League Cup win.

Arsenal 1 Birmingham 2February 27, 2011 l Att: 88,851

Another year and another Arsenal upset. Trophyless since 2005, Arsenal fell behind to relegation battlers Birmingham when Nikola Zigic opened the scoring. Robin van Persie levelled but a mix-up between Wojciech Szczesny and Laurent Koscielny allowed Obafemi Martins in to score.
